Commercial Mixer Amplifier

The JBL VMA1120 is a 120W mixer amplifier designed for commercial and restaurant installations. It provides a single amplifier output with configurable routing for 70V, 100V, 4-ohm or 8-ohm speaker lines. Bluetooth and USB playback are built in for background music or paging sources.

Five-Input Flexibility

The five input channels accept microphone, line-level and stereo RCA sources with individual bass and treble controls per channel. Voice-activated ducking automatically lowers music volume when a paging microphone is active. Installers who need more than one amplifier zone or additional input channels should consider a multi-zone matrix system instead.

120 Watt Output Power

The amplifier delivers 120 watts per channel into 4-ohm or 8-ohm loads and supports 70V and 100V distributed lines with 1 dB insertion loss. Frequency response reaches 20 Hz to 20 kHz on low-impedance outputs and 80 Hz to 15 kHz on high-voltage lines. Total harmonic distortion is rated at 76 dB below rated power.

Questions about this item

How can I confirm the 120 W amplifier is delivering clean power after installation?

Measure the output with a 2.83 Vrms signal into the rated load; the spec sheet shows 20 Hz–20 kHz ±2 dB on the 4/8 Ω tap and THD of 76 dB, so audible distortion should be negligible at normal levels.

Which cables or accessories must I source separately to use all five inputs and the 70 V speaker line?

The unit includes a rack-mount kit and front-panel controls; you will need Euroblock plugs for the mic/line inputs, RCA cables for stereo sources, 1/4″ plugs for additional line devices, and speaker wire rated for 70 V/100 V distribution.

Should I choose the 70 V or 100 V output tap for a restaurant paging system with long cable runs?

Both 70 V and 100 V taps are provided with 1 dB insertion loss; 70 V is standard for commercial paging in North America and reduces current on long runs, while 100 V is common in Europe — select the tap that matches local practice and wire gauge.
